I read about some of the ways to get rid of it, but most of them wont work without killing my fry anyways ( I have some fry in the tank and some in a breeding trap), raising the temp seemed to be the best option but I won't be able to remove all the fry that are already in the tank.

But I did remove the breeding trap and rinse it with hot tap water for 5 min (seemed to have helped)

I am going to refrain from feeding the mollies for a few days because they seem to be eating the hydra.
